The team bought a USB 3.0 analyzer from Lecroy. The chips and the tools still aren’t fully mature, so it’s not uncommon to find bugs. They have to compare across multiple platforms.

Once again we discussed Rent’s Law (same as on the show with Dave Vandenbout); there is a correlation with pin count and logic size. Dave and Mike want the opposite ends of the spectrum.

When asked about putting together an OSHW team, Mike said that he finds people at conferences and due to their contributions to the project before being hired. Many of the main contributors are now paid contractors.

Mike also recently attended the Colorado OSHWA meeting in Boulder. He got to meet one of the few science savvy US House Reps (Congressman Polis), who also was interested in the trend of open source. The remainder of the US congress still is pretty clueless.

Chris, I love tuvan throat singing. Have you listened to Gen Dos? It is wild, industrial genre, many overtones. Huun Huur tu is also very beautiful. Try listening to Sanskrit Storams next time you work, they are filled with wonderful algorithms behind the prose and grammar. I suggest the Sri Rudram.

Always great to hear Mike as a guest. Very excited about receiving my HackRF.

Hey chris, for the boost converter for the atx power supply idea, you can buy 12v -> +/-25-45v power supplies designed for putting large linear audio amps into cars, I’m sure it would be trivially easy to float one of the secondaries.

The fact that it’s bipolar on the output makes it even better. Could use that for an AB output stage or adjustable as the article above mentions. Might need some current limiting but this is a great start. Thanks!
